Functional Separability and the Existence of Consistent Aggregates in U.S. Manufacturing
提出一种基于间接生产函数的新方法，检验美国制造业中是否存在一致的实际增加值总体，克服了传统可分性检验的理论缺陷。
The traditional separability tests which are based on the translog production or cost function involve some drawbacks in terms of theoretical consistency as well as empirical implications. This study proposes a new method for testing functional separability, employing an indirect production function formulation and tests the existence of a consistent real value-added aggregate in U.S. manufacturing. Our approach provides a preferable alternative to the existing methods such as Berndt-Christensen's exact separability tests and Denny-Fuss' approximate separability tests in investigating the nature of separability.
